He did too much too soon after surgery.
That's what I think. And then I heard about him sleeping on the floor while he let the elder President Bush sleep on the bed in the plane. I thought "Nice of him, but couldn't be good."
Maybe his past drug use is the tell tell sign of a poor recovery.
Yep. It has nothing to do with "sleeping on the floor." That does not cause complications from heart surgery. Has anybody ever had their doctor tell them, after surgery: "do not lift anything over 5 pounds and do not, under any circumstances, sleep on the floor!"
Remember those three side trips he took when he was in Asia? To Japan, Taiwan, and South Korea? Maybe Hong Kong was in there, too? That's not close to the tsunami victims, and it was pressure on top of an already difficult trip. Just to do more book signings at $900 a pop per book. That wasn't very smart of him, especially when he already wasn't looking so hot.
